Reaktionsschritte
A typical sulfite electroplating bath is an aqueous solution including sodium gold sulfite, about 5 to 10 troy ounces per gallon (41.1 to 82.2 grams per liter) of sodium sulfite, and brighteners such as arsenic or cadmium metal in amounts up to about 500 ppm. The aqueous solution usually has a pH of 8 to 12 and contains between one-quarter to 3 troy ounces per gallon (2.1 to 24.7 grams per liter) of gold.
